Dear PCC~
Welcome to the Support Forum, a place where I'm sure many people have had to pass orals/roleplaying.
Not any people like roleplaying and it is only natural to be nervous, however it is the only way you are going to get practical expereince, and you will be very grateful for it later. Forget the class and concentrate on the client.
There are a few things to remember, in your first play the actor is not going to be the "client from hell," but will almost be cooperative, probably scattering clues. The assessors may find may things to comment one but basically want you to pass the aggregate of all your plays.
If the play has a subject, such as motivational interviewing or establishing your relationship or their suicide risk (yes, I'm just guessing) then you will be able to look up the main points of these and have them in front of you to remind you.
It cannot hurt to establish a relationship with the client, and the simplest way to do that is to ask them to talk about their situation and demonstrate you are listening and understand. Look out for danger signs to the client's welfare.
Practicing with another another student, preferably one who has done this before, would be an excellent idea.
I expect there will be many of these, so even if you do not get it all right the first time that simply means you learn and do better next time.
This may not apply here but in real life your own safety is paramount, you keep yourself closest to a door
Good luck, if you would like to say how you got on I'd be most interested
